Right. Unfortunately, I have MingW installed from official tarballs,

procedure from official tarballs I stuck with it.
What is happening is that I have an official MingW /bin/sh in my path
(which triggers MSYS), but the pathnames required by windows-side tools
such as MingW32 gcc are still Windows-ish (MingW).
AFAIK, if /bin/sh is in your PATH gmake goes into shell mode and you can
not use windows style shell stuff in the makefile. If you take out the
check that I put in, it should fail in some other way. I put the check
in early with a message to avoid people getting the weird errors later.
It does seem that there is an issue with allowing make.exe to work.
I think if you set CMAKE_MAKEPROGRAM to make.exe it should work.
Ok.
A patch that found different make.exe or make-mingw and then tested
them would not be rejected. I still don't see how we can avoid having
separate generators for MinGW and Msys, and I certainly don't think a
third one would help reduce confusion.
I'm assuming that the Msys generator is intended for the results of the
MSYS installer *.exe . As such, I'd prefer to assume the current MSYS
generator is known-good for that case. My impression (please correct if
inaccurate) is that it would be preferable to have the final patch
augment the MSYS generator to discern which filepath convention is
expected.
I don't see what case your 3rd generator will handle. Seems to me there
are only two cases regardless of how it was installed:
1. you have /bin/sh in your PATH and gmake runs commands via /bin/sh
2. you do not have /bin/sh in your PATH and gmake runs commands via the
native windows shell.
I wonder if the plain "Unix Makefiles" generator would work for you?
